Abstract:
A plasma display panel is provided with front and rear boards each having a plurality of electrode members, respectively. The front and rear boards are spaced apart to define a discharge space filled with an ionizable gas. The front board is equipped with a front glass plate including a fluorescent or phosphorescent element set on its inside surface, and a central plate having a number of holes therethrough. The electrode members of the front board are affixed by a coating to an inside surface of the central plate. The fluorescent or phosphorescent elements are placed at the rear of the electrode members on the central plate.
Abstract:
A gas-discharge display panel including slab carrying networks of conductors and an improved matrix, within the thickness of which the gas discharge takes place. The improved matrix is produced on the slabs carrying the networks of conductors, in the form of two sets of insulating strips oriented with respect to one another in order to form a rectangular pattern. These strips act as a spacer between the slabs.
Abstract:
There is disclosed a multiple gaseous discharge display/memory panel having an electrical memory and capable of producing a visual display, the panel being characterized by an ionizable gaseous medium in a gas chamber formed by a pair of opposed dielectric material charge storage members in contact with the gaseous medium, each dielectric being backed on the non-gas contacting side by an array of conductor (electrode) members, the conductor members behind each dielectric material member being appropriately oriented with respect to the conductor members behind the opposing dielectric material member so as to define a plurality of discrete discharge volumes constituting a discharge unit, the gas contacting surface of the dielectric material having a first layer of at least one oxide of Al, Ti, Zr, Hf, and Si and a second layer of lead oxide, both layers being applied to the surface in an amount sufficient to provide substantially lower and more stable panel operating voltages which do not significantly change with panel operating time.
Abstract:
This invention relates to a plasma display device adapted for generating a display in a color other than the characteristic color of the plasma gas utilized. At least one surface of each cell cavity of the device is formed at least in part of a multiphoton down-conversion phosphor (an anti-Stokes phosphor). For one embodiment of the invention the phosphor is coated on the walls of the cavity. For another embodiment of the invention, the cavity is formed as an opening through a member of an insulating material positioned between a pair of insulating plates, the plates forming the ends of the cavity, and the phosphor is incorporated into the material of at least one of the plates at least in the region thereof forming the end of the cavity.
Abstract:
The gas discharge panel disclosed in this application is composed of parallel electrode groups, a dielectric layer for covering the electrodes and a gas discharge space or gap in which a firing spot is produced through the discharge space via the dielectric layer when an electric signal is applied to the electrode pairs. The above-mentioned dielectric layers provide a suppression layer having a predetermined pattern which partially decreases leakage from the discharge field into the gas discharge space, that is, decreases the gas discharge in a position where a gas discharge is not required. In the gas discharge panel having a function of self-shift, this suppression layer has the form of a metallic strip, positioned at a right angle to these electrodes, or of a dielectric strip having a high dielectric constant, and constitutes a shift channel for the gas discharge spot. Further this supression layer is useful for carrying out a read-only memory type gas discharge by providing a predetermined pattern.
Abstract:
A gas discharge panel which has a shift layer for shifting a priming fire with a surface discharge and a display layer for memory and display when a discharge is produced between opposing electrodes. An equivalent electrostatic capacitance provided by a dielectric layer coated on the shift layer is made larger than that by a dielectric layer on the display layer to increase thereby a wall charge on the shift layer resulting from the surface discharge and decrease that resulting from the discharge between the opposing electrodes, thereby eliminating the possibility that an unnecessary priming fire for shifting is generated at the position of the discharge produced between the opposing electrodes.
Abstract:
A gas panel arrangement for storing, displaying, and selectively shifting information from one place therein to another includes an envelope filled with an illuminable gas, a plurality of vertical conductors disposed in parallel on one side of the envelope, a plurality of horizontal conductors disposed in parallel on the opposite side of the envelope with the regions of illuminable gas in the vicinity of the coordinate intersections of the vertical and horizontal conductors defining gas cells, and a writing arrangement which inserts binary information in a given portion of the envelope by igniting or not igniting the illuminable gas to represent binary ones and zeros. In order to accomplish shifting a sequence of signals is repetitively supplied to sets of the vertical conductors to shift binary information horizontally from one gas cell to another, and a sequence of signals is repetitively supplied to sets of the horizontal conductors to shift binary information vertically from one gas cell to another.
Abstract:
A water removable material ordinarily used as a brazing stop-off - i.e. to restrict the flow of a molten metal and thereby to prevent wetting of an underlying surface in a brazing or soldering process - has been found useful presently as a means to prevent oxidation of, or other damage to, terminal metallurgy of metallized glass components during protracted periods of baking, gas-filling and glass sealing processing incidental to fabrication of gas discharge display panel assemblies. The subject baking, gas-filling and sealing processing involves hours or even days of variant temperature treatment, which should be distinguished from seconds or at most minutes of brazing treatment. The protective function required of the water removable coating during this prolonged processing period is considered unique and eliminates certain application and removal process operations associated with the use of other protective media (e.g. sintered glass frit).
Abstract:
An addressable gaseous discharge device utilized for information display comprises a pair of spaced parallel oppositely positioned insulating walls forming between them a gas cell filled with ionizable gas. At least one of the insulating walls is transparent. The perimeters of the insulating walls are hermetically sealed. Field electrodes mounted on the insulating walls apply a microwave electric field to the gas cell and field electrodes mounted on the insulating walls partly and selectively apply a magnetic field in a direction crossing the microwave electric field. A glow discharge occurs in a selected part of the gas cell when the two applied fields meet the condition of cyclotron resonance of an electron.
Abstract:
A plasma-discharge display and data storage device wherein a glow discharge condition in a gas-filled, dielectric envelope is transferred from a region between a pair of transferor electrode conductors to a region between a pair of transferee electrode conductors by causing an AC voltage applied between the transferee electrode conductors to cause an associated potential field inside the gas-filled envelope to reach a glow-dischargesustaining magnitude prior to the time that the AC voltage applied between the pair of transferor electrode conductors causes an associated potential field within the gas-filled envelope to reach a magnitude sufficient to sustain a glow discharge; and a tapered electrode conductor in which a plasma or glow discharge in the gas occurs preferentially near the wide end of the tapered electrode conductor.
